This is for the B5.5, but it s/b the same principal for other TDIs
For OC, I am an old school bottom drain believer. Hot oil flow faster with gravity and brings all the foreign materials with it
vs oil xtractor - against gravity - and oil has to be warmed not hot so it won't soften the plastic tubing.
I used the oil xtractor to remove excess oil in the OFH etc.
Don't forget to do this. The valvetrain, turbo bearing, hyd. lifters etc. will tank you for it.
OF cap removed and OFH full of old oil
Pic.1
Old oil removed from OFH and completely cleaned. Anti-drain valve shown @ ~ 7 o'clock position
Oil will automatically drain to the crankcase as the OF cartridge/insert is removed
Pic.2
Insert filter, this will close the spring loaded anti-drain valve and add approx. 700 ml oil. This method is to replicate condition in pic.1 so no oil starvation to the valvetrain at first start. Better to pump oil than air to the valvetrain, turbo bearing, hyd. lifters no wear and tear.
Pic.3
Peace of mind. At first crank it pumps full oil not air to the valvetrain, hyd. lifters, turbo bearings etc.

1st TO PREFILL OFH WITH OIL IN THE CLUB
FFC
Fill FF w/ Diesel fuel. Very easy to do, no leaks, no air bubles, no spills
no priming required, no EFP cycling & wear and tear, always starts the 1st time
Fill to the bottom of the T-Static hsg neck. Lightly lubricate T-Static O-rings w/ Diesel fuel
before re-installing T-Static valve. Peace of mind for the injectors at first start as it will
get dose of fresh Diesel fuel not air
